MX934i Multiplex
PIR Intrusion Detector
Features
▶ Motion Analyzer II processing
▶ Unique address switch settings
▶ Insect and draft immunity
▶ Three sensitivity settings
The wall mount MX934i PIR Intrusion Detector uses Motion
Analyzer II signal processing to reduce false alarms. Alarm
and tamper conditions are transmitted to the control panel
through the two-wire multiplex bus. The detector’s
replaceable and pointable mirrors, three coverage patterns,
and three mounting options provide installation flexibility.
Functions
Motion Analyzer II Processing
Motion Analyzer II uses multiple thresholds and timing
windows to analyze timing, amplitude, duration, and
polarity of signals to make an alarm decision. It tolerates
extreme levels of heat and light disturbances caused by
heaters and air conditioners, hot and cold drafts, sunlight,
lightning, and moving headlights.
Insect and Draft Immunity
The sealed optical chamber provides immunity to drafts and
insects.
Three Sensitivity Settings
• Standard Sensitivity: Recommended setting for
maximum false alarm immunity. Tolerates environment
extremes on this setting. Not recommended for long
range or barrier type coverage patterns. The detector is
shipped in Standard Sensitivity mode.
•
Intermediate Sensitivity: Recommended setting for
any location where an intruder is expected to cover only
a small portion of the protected area. Tolerates normal
environments on this setting. This setting identifies
intruders more accurately.
•
High Sensitivity: Fast response to intruder signals. For
use in quiet environments where heat and light
fluctuations are not anticipated.

Installation/Configuration Notes
Compatibility Information
Control Panels Multiplex Expansion Modules
• DS7400Xi Series
• G Series
• DS7430
• DS7436
• D8125MUX
Note The DS7400Xi Series Control Panels require

Mounting Considerations
Select a location that is most likely to intercept an intruder
moving across the coverage pattern. Ensure the mounting
surface is solid and vibration free. Avoid hot and cold drafts,
windows, moisture, direct or reflected sunlight, and small
animals. The MX934i is not for outdoor mounting.
Note Misaligning the detector in an optional
mounting bracket can reduce range and
increase dead zones.
